A model for investigating e-governance adoption using TAM and DOI

Abstract

As governments around the world move toward e-governance, a need exists to examine citizens’ willingness to adopt e-governance services. In this paper, the authors identify the success factors of e-governance adoption by teachers in Greece, using the Technology Acceptance Model, the Diffusion of Innovation model and constructs of trust, risk and personal innovativeness. Two hundred thirty primary and secondary education teachers responded to an online survey. LISREL then analyzed the data. Model estimation used the maximum likelihood approach, with the item covariance matrix as input. A SEM validation of the proposed model reveals that personal innovativeness, compatibility and relative advantage are stronger predictors of intention to use, compared to trust, and perceived risk. Findings may enhance policymakers’ capacities by presenting them with an understanding of citizens’ attitudes.
